This invention relates to lubric'ating systems for internal combustion engines and the like and more particularly to; novel improvements in lubricating systems of the well-known splash type in I which the lower ends of the connectingrods splash or throw the oil to lubricate various niovin'g"parts' of the engine. V g V It is the usual practice to providein'inter nal combustion engines, having the splash or wipe system'ot lubrication, a pan or tray secured to 'tlie l ower half or bottom por tion of the crank case of the engine, and. to provide the pan or tray with" a series of depressions which, in effect, form oil troughs or receptacles, there being one trough for each connecting rod, so that the wipers or fingers'on the lower ends of the connecting rods dip iiito the oil in the troughs to splash or throw the oil fro m'the troughs and thus effect lubrication of the pistons, the bearings for the 'connectingrods, aswell as othermoving parts of the engine. The principal object of the present inventi on is to provide improvedand novel means for eilecting a proper and" substantially equal distribution' of the lubricant to the various receptacles ortroughs from which the lubricant is splashed up by the lower ends of the connecting rods'or the wipers secured thereto to perform that purpose.

Another object of the invention is to in; terconnect certain" of such O11 troughs or receptacles to assure the desired and proper ,distribution of the Oil to such receptacles.

A still further object of theinven'tion is toequip the pan or tray, equipped with the individual troughs fromi which'the oil is splashed, with adeflecting member so that as oil drains from a bearing, part of it is deflected or directed to grooves'in the pan for the purpose of distributing the oil to certain of such troughs It is also an Object of the invention to provide such deflecting member with @an: opening through which part of the oil, drip ping trom the crankshaft bearing, is de livered to the individual trough'bel ow the connecting rod adjacent the bearing.

It is an object of the invention to form in the pan or tray a groove on channel communicating or connecting certain ot the supplementary oil receptacles, and a second channel vor groove only connected to the supplementary receptacle, most remote from 1921. serial no. 463,185.

the defie cting" member or plate, so that part of the oil flowing-from the deflecting plate is conveyed to the; intercommunicating channelandpa-rt to'the channel only con nected to the receptacle most remote from the deflecting plate for the purpose 'oft'eeding more'oil draining from the bearinvention comprises'certain improved forms of construction, arrangementof parts, and combinations of elements which will be hereinafter more fully described and claimed, it being understood-that the present showing is intended to illustrate one form of the invention, which is susceptible of various modifications to suit special or varying conditions, and it will be further understood tha'tthe' terms whichl have used are merely descriptive and not limiting and that it is my intentionto include anynand all modification's'which come within the j scope of the invention," as defined by the appended claims. I a i In the accomjp'a'i'iyingdrawings I have illustratedone embodiment of the invention, in which:

Figure I' is a side view of an internal combustion engine-with the lower half in longitudinal vertical section to disclose'the structure embodying the present invention to" view.' 5 a Figure 11, is a detail transverse'section taken on the li ne' II I'I of Figure I.

Figure III is a horizontal section taken throughthe lowerhalt'of the crank case, as on the line III-III' of Fig. I, to show the supplemental'oil-pan or tray in top plan elevation.

Figure IV is a fragmental sectiontaken through the forward end ofthe supple: mental oil pan or tray, as on the line IVf-IV of Figure III.

Referring to Figural, it'will be observed that aconventionalform of engine with the crankshaft 10 mounted in the'bea'rings 11, 12 and 18; is shown, it being obvious however that the invention may be applied to any type or kind of niulti-cylinder internal combustion engine or the like. lmbricant may be supplied or fed to the crankshaft bearings through passages or ducts l-l, either by a force feed system, or by a gravity feed system, as desired, the lubricating system for :leeding oil to the crankshaft bearings not being; disclosed in the drawings, as any desired system may be employed for this purpose. lv'ipers or lingers e, the function of which will be described more fully hereafter. are secured to the lower ends of connecting rods 9 through which the pistons are reciprocated by the crankshaft.

The main reservoir for the lubricating oil for the engine is formed by the lower part 16 of the crank case, this lower part of the crank case being secured to the upper part by the usual means (not shown). 'lhe lubricating oil is drawn or carried from this main reservoir by any desired teni or means, as above mentioned, in order to lu brieate the crankshaft bearings through the conduits ll. It will be noted that the for" ward end of the c 'ank case part to engages in a groove formed in the underside of a portion 18 of the upper part. of the crank case, this portion being positioned under the front bearing Ll of the canikshaft. "lhe fly-wheel 19 of the engine is housed between the rear end of the crank case part 1U; and a vertical partition 20 secured at lower edge in any desired manner to the crank case.

A supplementary oil pan or tray positioned under the crankshaft of the engine so that the wiping or splashing;- devices 8, secured to the lower ends of the connecting rods 9. wipe or splash the oil from supplen'ientarv receptacles or troughs formed in the pan. This supplementary pan is formed of sheet metal and is stamped by suitable means to give it the required size, shape and contour. It is provided at its longitudinal sides with vertical ll: ig'cs 22 through which the pan is rigidly mounted in position in the crank case 16 by spotwelding, rivets or other suitable means. The rear end of the pan 1G is curved slightly u iuvard to form the flange or ledge :23, while the forward end is inclined upwardly and forwardly to form the flange 2%, which contracts with the forward end of the crank case 16. Under each connecting rod a depression, oval in plan view, is torl'ued in the tray or pan 21 to form a trough. or receptacle :25. Extending along the left hand side of the tray 21 and formed on one side by the flange 22, is a groove or channel '26 which, at its rear end. terminates in the rearmost trough 25, while the forward end terminates adjacent: or under the end of an angle plate or bar 30. which is spot-welded or otherwise secured to the forward flange of the tray 21. The

two intermediate troughs are connected by branch channels 27 to the groove 26, the channel 27 for the second trough 25 (count inp from the front of the ermine) being provided with a projecting portion 28. A channet or groove 29, which similar to groove 20, extends along the right? hand side of the pan 21, but the groove 29 is not connected to the intermediate receptacles 25, being only connected at its rear end to the rear receptacle. It will be observed by referring to Figures II and Ill that the grooves or chain nels 26 and 29 are ofuniform depth and more shallow than the receptacles 25. The plate 30, at its middle, is provided with an opening or hole 32 which is immediately above the forward middle end of the front receptacle Intermediate the first and second and the third and fourth receptacles 25, are openings formed in the pan 21, to permit the excess oil deposited on the pan to escape and drain into the main oil reservoir 1.6.

From the above description it will be clear that oil is carried or drawn from the main oil reservoi and supplied to the bearings of the crankshaft through the conduits ll. The oil which drains from the middle bearing 12, drips on to the pan 21 and, as the portion of the pan between the intermediate receptacles 25 is flat, this oil is free to (low in any direction, depending upon the inclination of the engine, it being directly distributed in this way, more or less equally, to the grooves 26 and 29 and the intern'iediate receptacles The oil from the front conduit l-ldelivered not only to the front main hearing but also has a free exit to the timing gears as shown clearly at the left of Figure I, so that a much greater quantity is delivered from the front conduit lel than from the interl'nediate and. rear conduits. It flows down on the portion 18 of the crank case and then on to the forward flange 2d of the pan :21 and the deflecting angle plate 30. Part of the oil draining from this front bearing, directcd or distributed by the deflecting plate to the channels 26 and 29, while the remainder escapes through the opening 3:2 in the angle plate 30 and runs into the forward receptacle 2:). The oil deflected to the channel 2G by the deflecting plate 30, flows from the channel to the three receptacles with which it communicates, while the oil conveyed to the channel by the deflect inn plate, flows only to the rear receptacle The wipers or splasher lingers 8, secured to the lower ends of the connecting rods, dip or wipe into the oil contained in the receptacles 25, whereby the oil is splashed to lubricate the connecting rod bearings and the cylinder walls, as is well understood in the art. The oil which is deposited on the lessee It will be observed, that the groove-23,

connected to three of the troughs-25, is formed in that side ofthe oil pan towards which the wipers or fingers Smove during the lower half of their revolution, a larger quantity'of oil being'splashed or deposited onthat side of the crank case, than onthe other side. It will also be seenthat the front receptacle25 does not communicate with either of the channels 26 or 29, it being supplied with suflicient oil from the front crankshaft bearing through V the opening 32 in the angle plate. The .oilfromthe rear bearing 13 for'the crankshaft'coes not drip or drain'ontov the pan 21, and there fore'in order to insure the proper distribution ofthe lubricant to therear receptacle, the channel 29 is provided to convey or transmit part of the oil, whichdrips onto the deflecting plate, and the oil, which is deposited on. the left side of the crank case and feeds into this channel, to this rear re- 7 ceptacle; By this novel arrangement of the intercommunicating channels or grooves and deflecting plate, a proper and even distribution of the lubricant to all of the receptacles-25 is effected in a most simple and eflicient manner. I,

The crank case 16 is formed to provide a sediment chamber 35 whichis closed by the screw plug 36 in theusual manner, this sediment chamber being provided to catch and retain any sediment or foreign particles which separates or settles out of the oil, the plug36,-of course, being removable to drain the oil out of the crank case. Secured over the top of the se'diinentchamber 35 byspotwelding orother means, is a sheet metal disc or plate 37 having a slot 38 and a lip or projection 39, the lip being stamped upwardly in the plate to form the slot. It

will be observed that as the sediment settles on the. bottom of the crank case 16, it will move rearwardly by gravity down the inclined bottom until it gets tothe slot 38, whereupon it will drop orsettle into the sediment chamber 35 andin this way be prevented from being again carried by the oil to the parts to be lubricated.

While I have illustrated and described one embodiment of my invention, it will be obvious that different modifications thereof may be constructed to suit different conditions, and. I wish therefore not to be restricted or limited to the precise embodiment. shown except in so far as the same is limited by the appended claims.
